Reloading 9mm Federal AE Brass (Problems)

This is a discussion on Reloading 9mm Federal AE Brass (Problems) within the Reloading forums, part of the Defensive Ammunition & Ballistics category; Well I started loading up some of my sized, belled and primed Federal American Eagle brass last night and well I have issues.
My Speer ...

Do your dies seat and crimp with same die or seperately,It sounds like you are overcrimping and crushing the case,back out the crimp die and then run a case with seated bullet up,then turn the die down until it stops,back case out and turn die down 1/2 turn more then crimp the case and check for crimp and feed in your barrel,may need a little more crimp to feed smoothly

Try measuring the case wall thickness at the point where your bullets seat.

Could be (I don't have any on hand to test) that the Federal AE walls are thicker. Multiply that by 2 and you might be getting too much crimp compared to other brass which might cause the cases to deform ?????

Actually that could very well be the problem, I did some Lapua Megashock JHP a few weeks ago using FC AE brass but these had the stepped in base on the projectile.

The FMJs im trying to use dont have this so as you say it might be very very tight.

I might keep these and build up a few hundred before I mess with my dies.

Currently ive got 1500 rounds of Speer Brass in waiting (loaded ready to shoot). and only 600 FC AE.

I've reloaded my 9mm brass with no crimping, you might make sure that your round is requiring a crimp. If you are crimping the round you could be over pressurizing the brass. Or the chamber of your gun is greater in diameter so the resizing dye is making your brass to small when you re size it. Get with a gun smith to determine a dye that works for your reloading needs. As for a crimping I strongly believe you are doing something that can be Very DANGEROUS. Consult to your book some have * to designate that a crimp is used. Be very careful and hope I've helped you on the problem.

Thank everyone for the feedback. I pulled back on the amount of crimp being applied and the Fed AE catridges went through nice and smooth. Also tried my speer ones on the same setting and they seem to like the setting as well.

Possible I was slightly overcrimping my last batch, but havent had any pressure or accuracy issues (thank godness as ive loaded 1000 or so).

Im loading at 4.65gr currently (max stated as 5.0gr) so should be within safety limits even with slightly overcrimped shells.
